Metcalf, 108-3. Two titles in 3 years. Easily the best record out of these guys. Some absolute studs on this list but 3 losses says it all. He also won one of the all time greatest brackets.
Remember Randy "Lewboo" Lewis made the NCAA finals as a true freshman. Due to the Brands/Va Tech-Iowa situation, Metcalf did not get to wrestle his full freshman season. Perhaps he would have only lost once, or maybe he would have picked up a couple more losses. He actually did lose 1 match as a true freshman, though it was by DQ in a tightly-contested match where he was struggling to score. Metcalf was always tough, but he definitely had a learning curve coming into college on his feet, and had a few little quirks to work out on the mat. Metcalf had a close 8-7 match as a true freshman against a kid from Maryland iirc. Nothing wrong with that, but I just point it out because Metcalf had a very offensive style where he was always trying to score points and physically overwhelm his opponent, so this result kind of indicates (at least one can interpret it that way) that he was not at that time the kind of wrestler that he would become a 1.5-2 years later. He was tough, yet beatable at this stage of his career.
I bring this up as a defense of Lewboo. He took 6 losses wrestling a full season as a true freshman in one of the toughest lightweight (126 and 134) eras in college history. It was every bit as tough, if not tougher than what Metcalf had to go through in his career. This gets lost with time, and recency bias works against Lewboo. In Lewboo's sophmore year, he went undefeated (36-0) and junior year he went 40-1, and won back-to-back NCAA titles. It was in Lewboo's senior year that he dislocated his elbow midseason against the great Jim Gibbons (whom he had beaten earlier that season) and that derailed the rest of his season though he was able to gut out a 7th at NCAAs. This is well-documented, ask some of the other boomers! Had that not happened, maybe he wins out and takes his 3rd NCAA title like he was projected to. Or maybe not. Some other things to consider: Randy Lewis won 74 matches in a row in college and had an unbeaten streak of 91 consecutive matches (had 1 draw vs. the great Darryl Burley- 4 time NCAA finalist and 2x champion, a wrestler he beat 4 times). He also made an Olympic team while in college. Lewboo's "hitlist" is a mile long. You'd likely be stunned by how many elite guys he's beaten, and he started beating them very early on in his career. They were both great, but I think I have to give the edge to Lewboo. He pretty much did every major thing Metcalf did, and a little more. I think the one thing that really gives Lewboo the edge is that he had an undefeated NCAA championship season, and Metcalf never quite achieved that. Undefeated championship seasons have historically been the gold standard. That is the only major strike against him (excluding the forfeited season), everything else between the two of them is more of a picking of knits.
Yes, I'm from the old school so I'll let you judge how much that is factoring into my assessment! Thanks for your time. : )
